Until recently, Shape Memory Alloys (SMAs) were predominantly developed for applications in the biomedical and engineering industry, and only a limited number of applications in textiles are known. Fabrics made of natural fibres (e.g. cotton, flax and their mixtures) present many advantages, such as wearing comfort, but they are subject to creasing. The aim of this study was to investigate the possibility of compensating for this disadvantage by using SMAs to create aesthetic low crease flax/cotton fabrics. Body Temperature SMAs (BT SMA) that regain their (straight) form when they are subject to human body temperature were used for this purpose. Clothing and bed sheeting are potential applications of these hybrid structures, which become wrinkle-free when they are exposed to the heat of the body, a hair dryer or that generated by an electrical current. The materials selected to achieve this purpose were the following: (1) textile yarns (e.g. single cotton or flax/cotton yarns, two-fold flax yarns and two types of loop fancy yarns) and (2) BT SMA wires of 300 um diameter. A power weaving loom and a hand-weaving shuttle loom were used to embed the SMA wires, and four types of hybrid fabrics were produced. The thickness, wrinkle recovery, dimensional stability as well as the cohesion of the SMA wires in the woven fabric were tested. All the tests were performed before and after a washing cycle for both the hybrid and reference fabrics. An increase in thickness was noticed after washing, and the recovery time after crushing varied according to the type of fabric. The slippage of SMA wires from the fabrics was noticed for all the samples, which was dependent on the type of yarns used, their linear density and the weaving process.

Jak dotychczas materiały z pamięcią kształtu były rzadko stosowane w wyrobach włókienniczych. Celem pracy było zbadanie uzyskania możliwości likwidacji zgniecenia tkaniny po ogrzaniu jej przez ciało ludzkie lub np. suszarkę do włosów. W celu uzyskania tego efektu wyprodukowano tkaniny do których wprowadzono druty ze stopu charakteryzującego się pamięcią kształtu (SMA). Zastosowano następujące materiały: przędze tekstylne - pojedyncze przędze bawełniane lub z mieszanek bawełny z lnem, podwójne przędze oraz przędze fantazyjne. W tkaniny wprowadzono druty SMA o średnicy 300 um. 4 rodzaje tkanin hybrydowych wykonano za pomocą krosien ręcznych i mechanicznych. Badano grubość tkaniny, odprężność zgniecenia, stabilność wymiaru jak również spójność drutów z tkaniny. Wszystkie testy przeprowadzono przed i po praniu tkanin. Stwierdzono wzrost grubości po praniu a czas odprężenia zależny był od rodzaju tkaniny. Stwierdzono również wyślizgiwanie się drutów z tkaniny we wszystkich badanych próbkach, zależne od masy liniowej przędzy, grubości tkaniny i procesu tkania.
